In most cases, the switched-mode power supply (SMPS) feedback loop regulates by observing the voltage at a specific point, while the remaining output voltage relies on the performance of the transformer to ensure proper operation. In this case, the stability analysis must include all secondary components to cover all possible load configurations. Needless to say, the traditional analysis method that covers all possible input / output conditions is difficult and time-consuming, and simplified analysis is prone to errors. This article will introduce a simplified method for multi-output power supply stability analysis using a SPICE simulator.
